Abstract
A direct voltage component of a signal which has been received and converted to a baseband is separated by a first separator in a signal line. Also the direct voltage components of both the signal preceding the separator and the signal following the separator are controlled by control signals. Thus a baseband signal line preceding the first separator can be direct current coupled.
